ABSTRACT

Disclosed is a system and method that allows users to customize audible and visible signals, such as music or video, to maintain a pre-determined or specified pace or to achieve a new pace in repetitive motion activities such as, but not limited to, running, walking, swimming, cycling, aerobics, and the like. Other applications of the system and method include, but are not limited to, enhancing the results of medical rehabilitation programs, physical therapy, weight loss programs, disc jockey services, and industries or manufacturing settings where repetitive motion is common and where audible cues designed to help users maintain a consistent pace are useful.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates generally to systems and/or methods forpacing individuals involved in repetitive motion activities to achievean optimal or desired performance goal. In particular, the presentinvention relates to hardware and software systems and methods thatallow individuals involved in repetitive motion activities such asrunning, walking, swimming, cycling, aerobics, and the like, to selectand use audible or visible information characterized by tempos thatmatch the individuals' repetitive activity tempo to increase the chancesof reaching an optimal activity level and complete an activity within adesired time period.

2. Description of Related Art

Devices for use by individuals engaged in repetitive motion activities,such as athletes, laborers, and artists, are known in the art. U.S. Pat.No. 4,164,732, for example, discloses a pacing device involving aportable frequency generator adapted to be worn by an athlete, thatemits audible tone bursts at selectable time intervals. The patentteaches that the device is used to train individuals, such as runners,to achieve a desired time goal for whatever repetitive motion activitythey are involved in.

There are many types of audible sounds that can be used for pacing anindividual, including simple tone bursts, as described above, theticking of a metronome, and the tempo of music, to name a few. U.S. Pat.No. 5,215,468, for example, discloses an apparatus for modifying thetempo of a musical piece and the output of an associated amplificationdevice as a motivational tool for joggers. The invention uses anadjustable drive motor to incrementally increase the rate at which themusical piece is played by the device, which is disclosed as being asubliminal change not noticed by the user. The patent discloses that theinvention may be used by marathoners and disc jockeys.

Pacing tools can be used to optimize the performance of an individualengaged in a repetitive motion activity once the individual's optimal ordesired pace is known or determined. U.S. Pat. No. 6,746,247, forexample, discloses a method for producing an instructional tool for anathlete that teaches the athlete appropriate rhythm, timing, and tempoby using the athlete's own best performance as a template to compose anew musical piece (as opposed to modifying an existing musical piece)having a specific tempo. The patent discloses that the athlete's tempois analyzed as he performs an activity, and then a song is composedhaving a tempo that matches the tempo of the analyzed activity and thatachieves an optimal level of performance of the athlete. The patentdiscloses that software may be used to modify the athlete's choice ofmusical piece, to include modifying the tempo of the musical piece andinserting pre-recorded notes or sounds, such as a metronome beat, intothe musical piece. An audio file player may be used to play back thetempo-modified musical piece to the athlete.

In addition to those pacing devices, other pacing systems incorporateinformation about the individual, his or her location, and the type ofactivity involved to further personalize and enhance the ability of theindividual performing the repetitive motion activity. Japanese PatentPublication 2004-113552, for example, discloses an exercise aid devicecapable of informing an exercising individual of an appropriate walkingtempo. The disclosed device calculates a walking pitch based on physicalinformation of the exercising individual and information about thecourse being walked. The device displays a list of music pieces having atempo nearly matching the individual's tempo, changes the tempo of aselected musical piece to match the calculated tempo, and plays thetempo-modified musical piece as the individual performs the activity.

Japanese Patent Publication 2003-108154 discloses a device and methodfor distributing music to a user based on received activity patterns(i.e., heart rate) relayed from a terminal device associated with theuser to a distribution device that selects and downloads to the user amusical piece from a database of musical pieces having a known tempo.The device and method are intended to facilitate an optimal level ofexercise by encouraging the user to exercise at the tempo of the musicalpiece such that the user's heart rate is maintained as close to apre-determined heart rate as possible. The reference does not disclosemodifying the tempo of the music pieces in the database.

Because different individuals perform at different levels of peakintensity for the same repetitive task, audible pacing tools have beenaltered in order to reflect each individual's movements. Where thepacing tool is music, an audible tone may be added to existing music orthe beats per minute of the music may be altered. U.S. Pat. No.6,448,485, for example, discloses digitally adding audible informationto an existing digital music data files.

What the aforementioned prior art systems and methods fail to address,however, is the need for a system and method for pacing individualsinvolved in repetitive motion activities that involves a plurality ofuser profiles and accessible music data files maintained by a networkedserver in data communication with a plurality of users' electronicdevices, each of the devices adapted to providing automatic locationinformation to the server and outputting audio and video informationthat the users can employ for pacing purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Several preferred embodiments of the invention are described forillustrative purposes, it being understood that the invention may beembodied in other forms not specifically shown in the drawings.

I. System Architecture.

FIG. 1 is a drawing depicting a schematic of the main systemarchitecture of a repetitive motion pacing system 100 according to oneaspect of the invention. The system 100 includes a user 102, which isshown as an individual but could be a group of individuals, a corporateentity, a governmental entity, or other person(s) or thing(s). Theinvention contemplates that the user 102 will have submittedinformation, in the form of an application, potentially with a fee, tobecome a subscriber of the system 100. The subscription provides theuser 102 with different levels, amounts, or degrees of access toinformation stored on a server computer (described below) associatedwith the system 100.

The user 102 can communicate with and receive information provided bythe system 100 using wired or wireless electronic devices 104, 106,and/or 108. The device 104 could be, for example, a wireless telephone,a wired telephone, a personal data assistant, or a portable computer.The device 106 could be, for example, a desktop computer. The device 108could also be a desktop computer. Combinations of those electronicdevices, or other types of electronic devices capable of sending andreceiving electronic, optical, and electro-optical signals, may be used.A separate data storage and music playback device, which is adapted toreceiving and/or sending electronic signals to/from devices 104, 106,and/or 108 and for storing and manipulating the electronic signals isdescribed later.

As shown in FIG. 1, the devices 104 and 106 are connected to a firstdata communications network 110, and the device 108 is connected to asecond data communications network 112. The particular connectivity ofthe devices 104, 106, and 108 to the first and second networks 110, 112is for illustrative purposes only. The network 110 may be, for example,a wireless network used by mobile computing devices like cellulartelephones. The network 112 may be, for example, the Internet, anintranet, or some other network system. Preferably, the networks 110,112 are packet-switched networks capable of routing hypertext,extensible, or other types of markup language code and data inaccordance with the standard Internet Protocol or some other protocol inorder to generate web pages. The Internet Engineering Task Force is thestandards body that creates and maintains the basic standards on whichthe Internet depends, including the Internet Protocol specificationpublished in 1981.

The first and second networks 110, 112 are connected or interconnectedto a server subsystem 114, which can include one or more servercomputers (not shown) that are adapted to, among other things, storingand processing data, generating responses to client computer requestsfor markup language files and information, and providing access to userinformation. The user 102 can use one or more of the electronic devices104, 106, and 108 to access the server subsystem 114 preferably via aweb site graphical user interface that is generated on the electronicdevices 104, 106, and 108, using markup language commands and dataprovided to those devices by the server subsystem 114.

The server subsystem 114 is capable of interfacing with one or moredatabases 116, 118, as shown in FIG. 1. The database 116 could be, forexample, a database containing records of each user's profile andpreferences. The user profiles may include personal information, suchas, but not limited to, the user's name, gender, height, weight, fitnesslevel, repetitive motion activities, duration of activities, physicaladdress, email address, stride length, distance to be covered, desiredgoal time, and desired goal pace. Personal information may also includehealth-related information, such as heart rate, pulse, calories burned,and other information. Preferences may include, but are not limited to,music artist, album, song title, and musical genre. In addition toincluding personal information and preferences, the user profile mayalso include subscription-related information, such as the type ofsubscription, fees paid and due, system access times and duration,physical and billing address information, and the number of downloadsfrom the system. The preferences may also include one or more rules,pre-defined by the user 102 or determined heuristically andautomatically by the system 100 over time as it “learns” the user 102.The rules define how the system 100 is to adapt to the user 102 whilethe user is engaged in a repetitive motion activity. The user profilemay also include address information associated with the electronicdevices 104, 106, and 108 used to access the system 100 and that receivedownloads, in-case-of-emergency (ICE) contact information, and technicalinformation about the user's data storage and music playback device,including system settings in case the system 100 is damaged, and othertypes of information.

The database 118 could be, for example, a database containing individualdata files. Preferably, the data files are music files, preferably in acompressed format, obtained from a user 102 or from a third partysource, although text and video files (or combinations of audio, text,and video files) are also contemplated as being within the scope of theinvention. The audio files may be stored in a single format, or multiplecopies of the file may be stored in a different format. The video filesmay include information for producing moving images of various routes auser 102 might run, walk, cycle, etc. Methods for converting audio (andtext and video) data files from one format to another are well known inthe art.

The server subsystem 114 includes a software subsystem 124, which willbe described later.

Also shown in FIG. 1 is a server 120 connected to a database 122. Theserver 120, which is shown connected to the network 112 but couldinstead be connected through some other data communications network, is,for example, a third party vendor computer system. The server subsystem114 can download music or other audio, video, or text data files fromthe server 120. Thus, for example, the server 120 could be associatedwith a major music production and marketing company that stores acatalogue of digital music pieces on the database 122. The server 120and database 122 are accessible by persons who agree to take a licensefrom the third party vendor.

It is also contemplated that the server 120 could be a computer in apeer-to-peer computer network. That is, the server 120 and the computer108 could be used to share audio, video, and text data files over thenetwork 112 in a peer-to-peer manner with each device operating as aserver and a client computer. The user 102 could then upload those datafiles to the server subsystem 114 and store them in the database 118.

As described above, the many objects of the present invention involveusing music or other types of audio and/or video signals to enhance oroptimize the performance of an individual engaged in a repetitive motionactivity. FIGS. 2-5 are graphs having curves that represent differenttypes of repetitive motions. For example, shown in FIG. 2 is a graph ofa repetitive motion activity that is represented by a sinusoidal curve202. The curve 202 is actually a series of individual points plotted ona time scale, t, having unit time period intervals t1, t2, t3, t4, t5,etc. Each point represents a level of intensity, I, associated with therepetitive activity. The curve 202 suggests that the intensity of theactivity increases sinusoidally over time from a minimum 204 to amaximum 206. One complete cycle of activity occurs over two time periodsand repeats continuously every two time periods.

FIG. 3 is another graph of a repetitive motion activity, this onerepresented by an impulse curve having individual impulses 302 a, 302 b,302 c, . . . , 302 n and impulses 304 a, 304 b, . . . , 304 n. Theimpulses are actually a series of individual points plotted on a timescale, t, having unit time period intervals t1, t2, t3, t4, t5, etc.,just like in FIG. 2. Each point can be related to a level of intensity,I, associated with the repetitive activity. The impulses suggests thatthe intensity of the activity increases immediately from a minimum point306 to a maximum point 308, levels off for a period of time, thenimmediately drops from the maximum point 308 to the minimum point 306.One complete cycle of activity occurs over two time periods and repeatscontinuously every two time periods.

FIG. 4 is another graph of a repetitive motion activity, this onerepresented by a line curve 402. The curve 402 is actually a series ofindividual points plotted on a time scale, t, as described above. Thecurve 402 suggests that the intensity of the activity increases overtime from a minimum point 404 to a maximum point 406 with anintermediate intensity point 408 that occurs for a portion of the cycle.

FIG. 5 is still another graph of a repetitive motion activity, this onerepresented by a complex curve 502 having multiple minimum levels ofintensity 504, multiple intermediate peaks of intensity 506, 508, and amaximum level of intensity 510. The periodicity of the curve 502 is thesame as the periodicity of the curves shown in FIGS. 2-4. Thus, a userengaged in any one of the repetitive motion activities represented bythe curves 202, 302 a, 402, and 502 could benefit from a motivationalmusical piece having the same periodicity.

In musical terms, the periodicity is related to the beats per minute(BPM) or tempo of the music. For example, FIG. 6 is a drawing of aportion of a musical piece 602 where the music is represented byindividual musical notes 604 grouped by even measures 608 (i.e.,measures of time). The tempo of the musical piece is indicated by themeter signature 606, which in the example in FIG. 6 is 4/4 tempo or fourbeats per measure. If the measure is two seconds, then there are fourbeats for every two seconds, or two beats per second (120 beats perminute). Music with a tempo in the range of about 120-130 BPM could beclassified as normal, while music with a tempo in the range of about140-160+ BPM could be classified as fast.

FIG. 7 is a graph of a sound wave represented by the line curve 702. Thecurve 702 has a periodicity of about two time periods. Each point on thecurve 702 represents an amount of pressure, P, at a specific period oftime. The upper part of the sound wave (i.e., the crest) at point 704indicates compression; the lower part (i.e., the trough) at point 706indicates rarefaction. The frequency of sound is the number of airpressure oscillations occurring at a fixed point in space, and ismeasured in Hertz (Hz). The human ear senses both the pressure changes,measured in decibels (dB) and frequencies (Hz) related to a sound wave.

The present invention includes a software subsystem 124, as shown inFIG. 1, which relates the pressure signals of sound as depicted in FIG.7 to the intensity levels of a repetitive motion activity as depicted inFIGS. 2-5. Preferably, the software subsystem 124 is adapted to modifythe tempo of music in such a way that the modified music matches asclose as possible the desired or optimal periodicity or tempo of theuser's repetitive motion activity. Sony's ACID® Pro software is anexample of a software product that can be used to modify the tempo ofmusic. Here, the distinction is made between a musical composition,which is a music piece that is generated completely new where there wasnone before, and a modification, which is an adjustment to specificaspects of an existing piece of music.

It is contemplated that the software subsystem 124, which could also beinstalled on one of the user's electronic devices 104, 106, and/or 108in addition to or instead of being part of the server subsystem 114, canalso be used to add sounds to existing music. Thus, a music piece thatdoes not have a discernable or obvious beat, such as a classical musicpiece having portions played pianissimo (very soft) alternating withportions played messa di voce (louder then softer), could be modified toinclude a metronome impulse sound, a voice prompt, a musical note, orsome other audible sound having the same tempo as the music piece, butthat is more obvious to the user 102.

FIG. 8 is a diagram of a graph showing, on the same time scale, t, acurve 802 representing the change in intensity of a repetitive motionactivity and a curve 804 representing the change in pressure of anaudible sound associated with music. The curve 804 is shown having ameter 806 of 4/4 tempo. The peaks of the two curves 802, 804 do notoccur at the same point in time. Thus, if the curve 802 represents theoptimal activity level of the user, the audible sound curve 804 is notsufficient to provide the pacing the user needs to achieve that optimallevel because the tempo of the sound curve 804 is too fast. FIG. 9 is adiagram showing the curve 802 as shown in FIG. 8, with a tempo-modifiedcurve 804′. Now, the curve 804′ has the same tempo as the curve 802.

In FIG. 10, there is shown a schematic of a data storage and music (orvideo) playback device 1002 for playing audio (or video) according toone embodiment of the present invention. The device 1002 may acommercially available iPOD®-like player or the like, modified toachieve the objects and advantages of the present invention. The device1002 may be portable or stationary (or parts of it may be portable andother parts stationary). For example, the device 1002 may need to beembodied in a lightweight, portable housing for a runner. In contrast,the device 1002 could be larger and integrated into the control panel ofa treadmill (or removable from the treadmill for use outside by therunner). The device 1002 could be made up of physically separablecomponents such that the audio speakers or video screen could bephysically attached to something, like the walls of a pool, while therest of the components could be transported to a different pool andconnected to different speakers/video devices. The device 1002 could beintegrated into a whole-house entertainment system. It could also beadapted to be an add-on component to existing storage and playbackdevices, which may include, but are not limited to, home, gymnasium, orhealth club, audio-video equipment and portable digital music players.The device 1002 could be part of a file sharing network, an on-demandradio or television service, a cable service, a satellite radio ortelevision service, a mobile phone network or other communicationssystem.

The device 1002 includes a main component 1004 which itself includescircuits and software associated with memory 1014, power 1016, amicroprocessor 1018, and communications 1020 subcomponents. It also hasan audio output device 1006, a data storage device 1008, optionally anAutomatic Location Information (ALI) device 1010, and an input/outputdevice 1012.

The communications subcomponent 1020 of the main component 1004 areintended to provide the device 1002 with the capability of communicatingdata from the device's permanent or volatile memory subcomponent 1014 toanother device via a wireless or wired data communications network.Thus, the communications circuits of the communications subcomponent1020 may be a modem with an RJ-11 jack for receiving a suitably-sizedcable plug for connecting the device 1002 to a traditional publiccircuit-switched telephone network. The communications subcomponent 1020may instead be a modem with a transceiver for sending and receiving datapackets over a wireless network.

The power subcomponent 1016 of the device 1002 can be provided byconventional power supplies (i.e., 110-volt service). Power may beprovided by rechargeable or disposable alkaline or other types ofbatteries (not shown).

The microprocessor subcomponent 1018 may be any conventionalmicroprocessor, such as a central processing unit of a computer.

Also shown in FIG. 10 is a data storage device 1008, which can be apermanent or removable hard disk drive, memory stick, memory card, orother conventional or miniaturized storage device that is operativelyconnected to the microprocessor subcomponent 1018 and memorysubcomponent 1014 within the main component 1004.

The audio output device 1006 shown in FIG. 10, which is operativelyconnected (i.e., by wire or wireless devices) to the main component1004, may include speakers associated with headphones or standupspeakers. For example, as suggested above, the speakers may be builtinto a treadmill, built into the walls underwater in a pool, or mountedon a wall in a gymnasium or home. The device 1002 may have multiple setsof speakers located in different places and each being used to playdifferent types of music. Thus, for example, the device 1002 may beconnected to five speakers, four of which play music while the fifthspeaker (such as a sub-woofer) plays or emphasizes the tempo of themusic.

One of ordinary skill in the art will appreciate and understand that theaudio output device 1006 could be a video output device, such as amonitor, light, or other device that produces visible signals that canbe sensed by the eyes of the user 102. Thus, light can be used toproduce pulses of light energy that the user 102 can detect while heperforms a repetitive motion activity.

The ALI device 1010 shown in FIG. 10, which is operatively connected tothe main component 1004, will preferably be used on portable devices.ALI devices are known in the art, and include GPS devices. A GPS deviceuses a receiver to receive telemetry data from a plurality of theconstellation of GPS satellites orbiting the Earth. The GPS device willinclude memory for storing the data, a microprocessor, and software forcomputing the location of the ALI device from the telemetry data. Anaccurate clock synchronized to the clock used by the GPS satellites isrequired to perform accurate location computations. The ALI device canalso rely on fixed terrestrial sources, such as mobile phone networktransmission/repeater towers and triangulation methods to identify thelocation of the device 1002.

The input/output device 1012 shown in FIG. 10, which is operativelyconnected to the main component 1004, could be, for example, a keypad ona mobile phone, a keyboard for a computer, a mouse, a touchscreen, atouchpad, a monitor, or other interface device that allows the user 102to input commands and allows the device 1002 to present information tothe user 102. It is also contemplated that the input/output device couldprovide an interface for a remote monitoring device (not shown), such asa heartbeat monitor, blood oxygen monitor, pedometer, or some otherdevice for monitoring the current state of the user. That stateinformation can be used to assess whether the device 1002 shouldmanually or automatically adjust the BPM of the music being played onthe audio output device 1006. For example, if the device 1002determines, based on the ALI-type information that the user 102 isslowing down and not maintaining his target pace, the device can warnthe user 102 using the audio output device 1006, for example, whichwould allow the user to user the input/output device 1012 to manuallyselect a different play list of musical pieces that are better matchedto the user's 102 current pace.

II. System Operation.

FIG. 11 provides a process flow diagram according to a preferredembodiment of the present invention. In process step 1102, a user 102interfaces with the system 100 by visiting a website through a networkedcomputer 108, wireless or wired phone 104, or by some other means asdescribed above. The system 100 then receives an electronic signal orsignals representing user profile information. If the user 102 is a newcustomer, a new user profile is created. If the user 102 is an existingcustomer, the user's existing user profile is modified.

The system 100 receives/updates user profiles when or after the user 102enters personal information using the input/output device 1012, such asa keypad or keyboard. For example, the user 102 may identify theactivity they wish to perform and their musical preferences. A web siteform can facilitate receiving that information. In addition, the user102 provides pace information (e.g., BPM) and may select music having acomparable BPM. That information is stored in the user database 116 thatmay include information provided at later dates by repeat users.

Personal information may also include, but is not limited to, the user'sname, gender, height, weight, fitness level, repetitive motionactivities, duration of activities, address, email address, stridelength, distance to be covered, and desired goal time. Musicalpreferences may include, but are not limited to, artist, album, songtitle, and musical genre. That information is stored in the user'sprofile as described above.

The system 100 receives the user's 102 comfortable pace, heart rate,calorie consumption rate, and other baseline or target information fortheir respective activities. In process step 1104, the user 102 candetermine this by performing a repetitive motion activity (i.e.,walking, running, swimming, cycling, lifting, stepping, etc.) for agiven time period, such as one minute, while counting the number ofsteps, strokes, pedal rotations, movements, etc., that he performs inthat time period. That information can be automatically or manually sentto the system 100, which receives the information and stores itautomatically.

The user 102 who visits the web site generated by the server subsystem114 may not know the pace or BPM he wishes to achieve for a particularrepetitive motion activity. Therefore, the system 100 provides the user102 a simple method of measuring a target pace, and prompts the user 102to enter that pace into a web form or otherwise provide the informationto the system 100.

For example, if the user 102 wishes to use music to pace him to adesired goal time or optimal level of performance over a discrete timeperiod, such as running a mile under five minutes or swimming 50 metersunder 30 seconds, certain information is required. First, the user 102must know the distance covered per each step, stroke, spin of a wheel,etc., which can be conveniently referred to as “stride length.” Thestride length over time is the stride period. FIGS. 2-5 graphicallyillustrate various types of stride lengths over a given time period (thepeak intensity represents a complete stride period).

The present invention includes a simple method for the user 102 todetermine his stride length. Stride length can be determined by manydifferent methods including, but not limited to, the following:

Mathematical Determination. A user 102 mathematically determines hisstride length on a course of specific length such as 100 meters, a mile,etc. This is illustrated in FIG. 12, which shows a user 102 running on astraight course 1202 having a pre-determined geographical start S andfinish F location. Mathematically determining stride length is possibleif the user provides the number of steps/repeated motions in a giventime period, such as one minute, as well as the time to complete acourse of specific length such as 100 meters, a mile, a kilometer, etc.As shown in FIG. 12, the distance between the user's steps, which arerepresented by the impulse lines 1204, is not consistent, so the stepsper unit distance should be an average.

Body Measurement. A user 102 estimates his stride length by taking bodymeasurements such as the length from his hip to his ankle, or fromfingertip to shoulder.

Average Stride Length. A user 102 refers to a provided table to estimatehis stride length, based upon data elements such as height, weight,gender, fitness level, etc. These tables may be provided on the web sitegenerated by the server subsystem 114.

Geometric Measurements. A user 102 measures the distance or otherphysical parameter associated with a repetitive motion, such as liftingand moving a box as illustrated in FIG. 13. The user 102 measures thedistance to complete the task between the start of the task at point Band the end of the task at point E. The time to complete a singlerepetitive task can be measured as a continuum over the distance B-E, asillustrated by the curve 1302, or as a fraction of the continuum, asillustrated by the curve 1304. Measuring the time to complete a singletask as in curve 1304, where only a fraction of total time requiresestimating extra time to account for errors and imprecision in thesystem, distractions, and windup and let down time before and after eachtask, which may be important in industrial settings.

Referring to FIG. 11 again, in process step 1106, the user's location isdetermined in real-time or near real-time using any means for obtainingALI-type data. A combination GPS telemetry receiver and software forcomputing location is one such means for obtaining ALI data. Many mobilephones and computing devices have integrated GPS technology. The presentinvention contemplates the use of a portable music storage and playbackdevice 1002 having an integrated GPS receiver or is otherwise adapted tooperatively connect to or interface with a separate GPS receiver. Atouchpad at the ends of a pool lane could be used to estimate locationinformation of a swimmer. Other electrical-optical-mechanical sensingdevices, including biometric sensing devices, could also be employed,for example in a work environment, to identify the location of the user102.

The ALI data can be converted into a suitable signal and automaticallysent to the system 100 over the first or second data communicationsnetworks 110, 112 (FIG. 1). The system 100 receives the ALI data andstores it automatically. Ideally, time-stamped three-dimensionalgeographic location information (i.e., latitude, longitude, altitude,and time) are determined on a regular basis and sent by the ALI device1010 (FIG. 10) and received by the system 100.

Another exemplary means for obtaining the location information of theuser 102 involves a geographical information system whereby the userpre-selects routes of travel (e.g., a trail or road course) and, alongwith pacing information from the user's user profile, an approximategeographic location of the user 102 can be estimated and received by thesystem 100. Thus, if the user 102 intends to traverse a one-mile loopover relatively flat terrain identified on a conventional topographicmap at a 20-minute per mile walking pace, the approximate location ofthe user 102 can be determined over the course of the 20-minute activityperiod using simple mathematical calculations.

In process step 1108, once the user 102 has determined or estimated hisstride length, the system 100 receives that information via thenetworked electronic devices 104, 106, 108, as described above, using aninput/output device 1012 (FIG. 10). The system 100 will use the stridelength information to identify which song or combination of songs arebest suited to meet the pacing needs or time goals for specificdistances such as a mile, a kilometer, etc., and that satisfy othercriteria specified in the user profile. The system 100 will make thosesongs available for download by the user 102, or will automaticallydistribute the songs to an address designated by the user 102, such as aweb site address, an e-mail address, a mobile phone number, or someother pre-selected destination address contained in the user profiledatabase or provided manually by the user 102.

The system 100 maintains a separate song database categorized accordingto variables including, but not limited to, title, artist, genre,duration (minutes and seconds), BPM, etc. After obtaining specific datafrom the user 102, the system 100 cross-references user profile data,pace data, activity goals, and musical preferences with the songdatabase to identify songs that match the needs of the user 102. Forpacing purposes, a desired pace in steps, pedal strokes, arm strokes,and the like per minute and a song's BPM must be substantially or atleast approximately equal. Songs in the database that match the desiredpaces and musical preferences of the user 102 are presented to the user102 in a menu of choices. The user 102 chooses the songs they wish todownload and use for pacing purposes.

In some cases, the user 102 may wish to download a song for pacingpurposes that does not have a BPM that matches his pacing needs. If thesong falls within an acceptable range above or below the target BPM, itis possible to modify the tempo of the song to the desired pace asdescribed above. Using readily available software, like Sony's ACID®Pro, a song's BPM can be altered easily without changing the pitch ofthe music or negatively impacting the audio quality if the song is in anappropriate digital format.

In process step 1110, if the user 102 requires that a song be modifiedto match a desired BPM, the following steps are performed. First, afterthe system 100 receives and creates a user profile containing personalinformation, desired activity, musical preferences, and desired paceand/or goal time, among other things, the system 100 cross referencesthe pace information and other preferences with a song database. Songsthat are a direct match to the BPM preferences and other criteria (e.g.,genre) selected by the user 102 are placed on a menu of choices. Songsthat fall within an acceptable range above or below the target pace, andwhich match at least some of the user's criteria, are also placed on themenu of choices. The user 102 then selects the songs that he wishes todownload and the system makes those songs available or delivers thesongs as described above. Songs that already match the desired BPM canbe automatically downloaded to the address provided by the user 102 inhis user profile (i.e., the address can include, but is not limited to,a phone number, an Internet Protocol address, or any other addressablelocation). Songs that require tempo modification are processed throughseveral additional steps either by the system 100 or by the user 102before they are used.

Songs requiring tempo modification are transferred to a tempomodification program that automatically reads the BPM for that songeither from the ID3 tags associated with the song, from the songdatabase, from a vendor that provided the song, or from some otherlocation in the system 100. ID3 is a metadata container most often usedin conjunction with the MP3 audio file format. It allows informationsuch as the title, artist, album, track number, or other informationabout the file to be stored in the file itself. Most software musicplayers for the PC allow the user to view and edit the data in an ID3tag. The user 102 may download songs requiring tempo modification,import them into a tempo modification software program, modify them, andthen add the songs to their play list or portable audio player. Thedesired goal or target BPM for the song is obtained from the user's datastored in the user profile database or is provided separately by theuser 102. After a song is loaded into the tempo modification program,and the program understands the original BPM and target BPM, the programmodifies the song's tempo to the desired BPM as illustrated in FIGS. 8and 9. Additional information can be electronically added to the songdata, such as, for example, a repeating metronome beat, a highlightbeat, or a word (e.g., “step” or “go”). The pitch of the song is heldconstant during this process, and the song is modified withoutnegatively impacting audio quality. The new, modified song file is savedand the data file is made available for download or is automaticallydelivered to the address specified by the user in an appropriate digitalformat.

The invention can be used by musicians to provide their original musicto the system 100, which any user 102 can then select for his pacingneeds.

In process step 1112, the system 100 provides the songs (either originalor modified) to the user 102. This can be a free- or fee-basedtransaction based on a subscription or pay-as-you-go model. The user 102downloads his customized music to his electronic device 104, 106, and/or108 (FIG. 1), automatically to his portable storage and playback device1002 (FIG. 10), a web site server, or to some other device for transferonto a portable music player. The user 102 then listens to the songs topace himself to achieve potentially to a desired completion time for arepetitive motion activity.

FIGS. 14-16 illustrate various uses of a portable data storage and musicplayback device 1002 according to one aspect of the invention. In FIG.14, shown therein is a path 1402 in relation to a coordinate system x(representing a linear dimension). The path 1402 can be defined by alinear distance between spaced-apart points S and F. The path 1402 canbe further defined by a finite number of linear path segments A, B, Cand D, which, in the case of FIG. 14, do not overlap with each other.For description purposes, assume path 1402 between points S and F is50-meters long (i.e., the length of a lap pool), and path segments A, B,C, and D are 10-meters, 8-meters, 7-meters, and 15-meters, respectively(thus, they add up to 50-meters or the total length of the path 1402).The user 102 swims 50-meter laps and listens to music (or observes lightpulses) having a constant BPM tempo that has been adjusted specificallyto the user's swim stroke so that he can maintain as constant a strokeas possible toward the goal of completing 50 meters within a set timeperiod.

The device 1002 can also be programmed so that the BPM of the musicautomatically changes slightly with each 50 meters completed, so that asthe swimmer tires, he will still be able to achieve the time goal.

The device 1002 can also be programmed so that the BPM of the musicautomatically changes in each path segment, so that the BPM of segment Ais faster than the BPM in segment B, C, and D, for example. Thus, thedevice could be used by competitive swimmers, runners, and walkersduring fartlek training, which is an athletic training technique inwhich periods of intense effort alternate with periods of less strenuouseffort in a continuous workout. Thus, the BPM of the music assigned tosegments A and C could be twice the BPM of the music assigned tosegments B and D.

FIG. 15 illustrates another path 1502 in relation to a coordinate systemx, y. The path 1502 can be defined by a start position S and a finishposition F, which are the same geographical point in space. The path1502 can be further defined by a finite number of path segments A, B, C,D, and E which, in the case of FIG. 15, do not overlap with each other.For description purposes, assume path 1502 is a 10-mile road and trailroute that the user 102, training for a marathon, regularly traverses aspart of his training regime. FIG. 16 illustrates the same route in thevertical z dimension and shows the altitude changes that the userexperiences over the course of the route. Segment C is a hilly portionof the course and involve a slower switch-back portion up a longhillside through the woods. The geographical coordinates at discretepoints m, i.e., (x′, y′, z′), and n, i.e., (x″, y″, z″), along the routeare stored in the memory subcomponent 1014 of the device 1002.

Thus, the user 102 carries his portable data storage and music playbackdevice 1002 during the 10-mile run, and, because the device 1002 isequipped with an ALI device 1010, the system 100 automaticallydetermines the user's real-time or near real-time geographic locationalong the route 1502 and compares the location to the discrete locationsstored in memory. When the user 102 sets out running in segment A, whichis a flat road segment of the 10-mile route, the device 1002 plays aspecific song having a BPM tempo that is consistent with the pace theuser wishes to maintain. However, when the user 102 reaches the off-roadsegment B, the uneven footing requires a slower pace, so the device,knowing when the users enters segment B by comparing the ALI data to thestored location information, changes the BPM of the song or plays adifferent song having a slower BPM. When the user reaches the twistysegment C, which is the slowest segment of the 10-mile route, the device1002 begins playing a song having a slower BPM to match the user's shortstride length as he traverses the hilly segment C.

The system 100 also has an adaptive capability that supports a user 102who, for example, is running and having trouble keeping pace with hismusic. The user 102 may wish to reduce the pace by changing the music heis listening to. The user 102 might have included a rule in his userprofile that governs the songs being played by the portable data storageand music playback device 1002. The aforementioned GPS feature in theportable data storage and music playback device 1002 will recognize thatthe user's 102 pace is dropping off, causing the device 1002 to switchto a slower play list based upon the rules entered by the user 102. Theportable data storage and music playback device 1002 itself may providethe user 102 with a manual switch that causes the BPM of songs to becomesmaller or to play the song slower.

Another example of the adaptive capabilities of the system 100 is asfollows. Consider a user 102 who uses a mix of music to complete aroute. The user 102 might wish to improve his time the next time hetraverses the route by 5%. The system 200 allows the user 102 to submitthis request to the device 1002, spurring the system 100 to tempo modifythe user's 102 existing mix to be 5% faster than before or automaticallyprovide a new selection of songs that is 5% faster then the previoussong mix.

Another example of the method of using the system 100 is as follows.FIG. 17 is a diagram of a repetitive motion activity device 1702 beingused by a user 102 engaged in a repetitive motion activity. The system100 may be an integral part of, or interconnected to, the separaterepetitive motion activity device 1702, which in FIG. 17 is a treadmill,but any device, such as a stair master, elliptical machine, and thelike, can be used. The device 1702 can determine a speed or rate ofrotation of the separate device based on the tempo of the music or videobeing played on the portable data storage and music playback device1002. In other words, as a song plays, the device's 1702 computerrecognizes the BPM of the musical piece or video being played andautomatically adjusts the speed or rate of rotation of the device 1702to accommodate the song's pace. The user 102 could fine-tune the speedor rate of rotation as well to allow for any variations in his stridelength that the separate device cannot automatically sense.

Another example of the method of using the system 100 is as follows. Asnoted above, the system 100 may be a integral part of, or interconnectedto, a separate repetitive motion activity device 1702, such as atreadmill. The system 100 will provide a video feature whereby videoimages of locations where a user 102 runs, walks, cycles, climb stairs,etc., are displayed on a video screen 1704 in front of the treadmill orother repetitive motion activity device 1702. The frame rate of thevideo is be automatically calibrated to match the speed of the user's102 pace, speeding up when the user 102 increases his pace, and slowingdown when the user 102 slows his pace. Or, the video files may containinformation that produces images representing a route the user 102 mightrun, walk, cycle, etc., such as, for example, the route as shown in FIG.15. The video files would be linked the database of information storedfor path 1502 such that the tempo of the repetitive motion activitydevice 1702 and the video being displayed change to reflect the pathsegments A, B, C, D, and E in order to simulate what the user 102 wouldhave experienced if he had actually traversed the actual path 1502.

The ALI device 1010 can also provide information about the user 102,such as total distance traversed over time, average pace, locations,calories burned, etc., which information can be uploaded to the system100 and stored in the database 116 as part of the user's user profile.

The ALI information can also be employed in industrial settings where,by knowing the location of the user 102, the system 100 and device 1002know what activity the user 102 is engaged in. Thus, when the system 100recognizes that the user 102 is located at position P1 within a factory,based on ALI information it receives from the ALI device 1010, andposition P1 is a conveyor system, the device 1002 plays a pre-determinedBPM associated with the tempo of the conveyor system. When the system100 recognizes that the user 102 is located at a new position P2 withina factory, and position P2 is a truck loading area, the device 1002plays a different pre-determined BPM associated with the tempo of theloading area.
